Electric heating can serve a room, a workstation or an entire building. The appropriate technology depends on heat demand, use and the available electrical supply. Modern controls do not automatically make every electric appliance cheaper to run than gas or a heat pump.
We discuss infrared panels, convectors and electric underfloor heating, while including heat pumps as a comparison. This lets you assess comfort, installation and total costs without relying on blanket savings promises.
Key considerations
Start with heat loss and occupancy schedules. Distinguish electrical resistance heating from a heat pump. Compare systems for the same comfort requirements and check supply, mounting, controls and maintenance for each model.
What is electric heating?
With resistance heating, almost all electricity consumed ultimately becomes heat in the building. This applies to many older appliances as well as modern panels and convectors. High conversion efficiency therefore says little about the electricity needed to keep your building comfortable.
A heat pump also transfers heat from the surroundings and can therefore deliver several units of heat per unit of electricity. Actual seasonal performance depends on the system and conditions. Compare this performance with direct electric heating for the same heat demand.
Going gas-free also requires solutions for hot water and any other gas uses. Standing gas charges only disappear when the connection is actually terminated. Solar panels do not automatically make winter heating self-sufficient or carbon-neutral; generation, simultaneous consumption and grid imports still matter.
Comparing infrared, convection and underfloor heating
Infrared panels emit radiant heat and also transfer heat by convection. People and surfaces within range receive radiant heat while the air also warms. A convector mainly transfers heat to the air; not every convector has a fan. Both technologies require suitable capacity and controls.
Electric underfloor heating first warms the floor assembly, which then releases heat into the room. Construction, insulation and floor finish influence response time and permitted temperature. Distinguish this from hydronic underfloor heating, which may be supplied by a heat pump and has different energy use.
A combination may be useful when background heating and local comfort serve different purposes. Coordinate their controls. Running two systems does not automatically save energy, and none of these heaters replaces ventilation or removes airborne allergens.
Assessing consumption and costs
Determine heat loss at the desired indoor temperature and relevant outdoor conditions. Insulation, glazing, ventilation, adjoining spaces and use all matter. A generic wattage per square or cubic metre cannot establish suitability for your room. Insufficient capacity may compromise comfort; extra capacity does not guarantee lower consumption.
For an appliance with fixed input power, electricity use equals power in kW multiplied by actual operating hours. Multiply kWh by your tariff to estimate costs. For a heat pump, use expected seasonal performance. Include purchase, installation, controls, maintenance and any electrical upgrades.
Zoning and schedules can reduce unnecessary heating when matched to use. Wi-Fi, adaptive start and open-window detection depend on the model. Check sensor placement, load, compatibility and fault behaviour. An app or precise temperature display does not prove a fixed savings percentage.
Let the application determine the equipment
For living rooms and bedrooms, assess occupancy, desired temperature and placement relative to furniture and people. Check the finishes actually available for decorative, photo or coloured panels. Noise, lighting and operation vary by appliance and controls.
In a bathroom, the model, mounting position and complete electrical connection must suit the conditions. An IP rating alone does not authorise every location. A heated mirror is not completely condensation-free under all conditions. Heating does not replace moisture extraction or repairs to leaks.
In offices and halls, workstations may have different heating needs from storage or circulation areas. Assess working height, occupancy, obstructions and any particular hazards. A domestic panel is not automatically suitable for a tall industrial building; industrial heaters have their own installation and operating requirements.
Quality, installation and maintenance
Assess the actual product through documentation, permitted use, finish, warranty and spare-parts availability. European origin or a CE marking does not by itself prove superior performance or independent product testing. For a certification mark, check the specific model and the scope of its evidence.
Follow the selected model’s instructions for fixing, clearances, orientation and connection. Have the supporting structure, existing circuits and simultaneous load assessed. There is no single power threshold above which an entire home always needs exactly one additional circuit. Have fixed wiring carried out by a competent installer.
Low maintenance does not mean maintenance-free. Follow instructions for cleaning and checking the appliance, connections and controls. Consider hot surfaces and vulnerable users. Service life and warranty are different matters; without model-specific evidence, we do not promise fixed lifetimes or maintenance savings.
A heating plan for your building
We help private and business end users choose equipment and support installers and wholesalers. Share a floor plan, insulation details, occupancy schedules and information about the existing installation. We can then discuss missing information and the equipment, controls and work to include in a quote.
Frequently asked questions
Which electric heating uses the least energy? This must be assessed for a particular application. Compare heat pumps and direct electric appliances for the same heat demand. A low purchase price or a high radiant fraction does not prove the lowest running costs.
Can my whole home go gas-free? That depends on heat loss, comfort requirements, electrical capacity and hot-water provision. Have the complete plan assessed before removing the existing heat source or gas connection.
Does infrared improve air quality? A heating panel is not an air purifier and does not guarantee a dust-free or healthier room. Air movement continues. Ventilate, limit moisture sources and address the causes of damp or mould.
